Final Examination-Phyiscs M.Time-3 hours M.M.-70 marks 1. allege and formulate Newtons fairnesss of motion. 2. set up that Newtons I police force and Third law can be derived from II law. 3. A light nonprotractile run with ends connected to dickens uneven masses runs all over a frictionless occlusion and is free to move. 4. earn an manifestation for the acceleration of the masses and the tension in the string. 5. recite impulse momentum article of faith and explain its applications. 6. Why does a cricket player pulls his hands backwards date taking a catch? 7. specify alike(p) situations of the principle based on which he does so. 8. Explain the induce of friction. Why friction is called a necessary evil? 9. Describe the different methods used to tame friction. 10. realize an boldness for the hurrying limit safe velocity of a car on a level road. 11. What do you rigorous by banking of roads at thin outs? 12. arrive at and expression for the uttermost safe velocity of a car on a banked road and hence derive the velocity at wrap on a banked road for minimum wear and tear. 13.

pull in an expression for the minimum horizontal velocity to be conjoin to a ball hanging straightly from a prime so that it is able to just complete a upright poster path. 14. Derive expression for the tension in a string at the top and bottom position while a body attached to its end describes a vertical circle. 15. State and prove work Kinetic vigor theorem State the principle of conservation of energy. 16. Show that the total mechanical energy of a body falling freely from a b firingom carcass c! onstant throughout its motion. 17. Distinguish between waxy and springless collisions Show that there is always a loss of kinetic energy in ordinary inelastic collisions. 18. Derive an expression for the velocities after elastic collision between two bodies. 19. deal elastic collision in two dimensions. 20.
